From the BBC:

The rapid rise in food prices could push 100m people in poor countries deeper into poverty, the head of the World Bank, Robert Zoellick, has said.

His warning follows that from the leader of the International Monetary Fund, who said hundreds of thousands of people are at risk of starvation.

Mr Zoellick proposed an action plan to boost long-run agricultural production.

There have been food riots recently in a number of countries, including Haiti, the Philippines and Egypt.

"Based on a rough analysis, we estimate that a doubling of food prices over the last three years could potentially push 100 million people in low-income countries deeper into poverty," Mr Zoellick said.
